A SIM card is the small plastic chip that you insert into your phone. It contains all of the information needed to allow you to connect to a mobile network.
An eSIM is simply a digital, software version of that. Most modern smartphones or cellular devices have already got an eSIM built into them, so Instead of inserting a second (plastic) SIM into your device when you travel, you can simply download an eSIM with an international data plan directly to your phone or device.
Travel eSIMs are designed to work alongside your normal mobile plan, not replace it. As the name suggests, the travel eSIM provides the mobile data you need when travelling abroad.
Because everything is digital, there’s no need to physically swap SIM cards or visit a shop, or vending machine when you arrive in a new country. You simply download and install the trvllr. eSIM before you travel*, add some funds to your trvllr. wallet, and your international data is there when you need it.
In simple terms, a travel eSIM keeps your phone connected to the internet while travelling, so you can continue using things like WhatsApp, email, maps, streaming, and your favourite data apps wherever you are.
*if you have already travelled and want to download and set up your trvllr. eSIM, make sure you are connected to wifi first
Good question... Not every traveller is using travel eSIMs yet because the market is still very confusing, poorly explained, and often mistrusted. Many people don’t fully understand what an eSIM is, or they assume it’s complicated to set up, while others have been put off by misleading pricing, confusing “unlimited” claims, and inconsistent experiences across providers.
On top of that, habits are hard to break, people stick with using wifi, roaming or airport SIMs because it feels familiar and safe, even if it’s not the best value. Until the industry becomes clearer, more transparent, and easier to trust, a large proportion of travellers will continue to avoid it altogether...
The industry itself has a name for this demographic... it calls them "silent roamers".
